Reconstruction of the Central Zagros paleo climate and paleo environment
Introduction The study of lake sediments has been widely used in recent decades to identify past climate and environmental changes. Lake basins have significant spatial and temporal patterns and provide valuable evidences of physical and chemical changes. However, in general, the climate of the Holocene period has been more stable and uniform than previous glacial and interglacial periods. How...
متن کاملThe Paleo diet and diabetes.
151 T and defects in insulin secretion. Obesity is the major risk factor for the development of the condition and a number of studies— including the Diabetes Prevention Program, the Da Qing IGT and Diabetes Study, and the Finnish Diabetes Prevention Study— have shown that lifestyle modification (diet and exercise) can significantly prevent the progression of glucose intolerance (prediabetes) to...
متن کاملHigh-resolution record of geomagnetic secular variation from Late Pleistocene Lake Lisan sediments (paleo Dead Sea)
We measured geomagnetic secular variation in Lake Lisan sediments (paleo Dead Sea). More than 1500 oriented samples were collected from a 27.3-m section of alternating aragonite and detritus laminae in the Dead Sea basin ranging in age from 67 to 32 ka. The natural remanent magnetization (NRM) is carried by titanomagnetite in the detrital laminae whereas the aragonite is diamagnetic. The NRM is...
متن کاملAnalysis of river sediments in the paleo- Meyghan basin
Introduction The territory of central Iran is now affected by the hot and dry climate. But, several evidences, such as the extreme erosion of running waters, huge alluvial fans, wide alluvial terraces, and flood deposits indicate colder and wetter climate in the territory (Ghahroodi Tali, 2011: 3). The rivers belong to the most important parts of the sedimentary basin. In fact, the rivers are...
متن کاملPaleo-perspectives on ocean acidification.
The anthropogenic rise in atmospheric CO(2) is driving fundamental and unprecedented changes in the chemistry of the oceans. This has led to changes in the physiology of a wide variety of marine organisms and, consequently, the ecology of the ocean. This review explores recent advances in our understanding of ocean acidification with a particular emphasis on past changes to ocean chemistry and ...
